An edifice or structure of heavy timbers or logs for military defense, having its sides loopholed for musketry, and often an upper story projecting over the lower, or so placed upon it as to have its sides make an angle wit the sides of the lower story, thus enabling the defenders to fire downward, and in all directions; -- formerly much used in America and Germany.
A thick-walled concrete bunker to protect personnel from explosions. Usually houses the electronics for a missile launch.
Usually a two story wood building with an overhanging second floor and rifle loops and could also have cannon ports (embrasures). Some three story versions. Some with corner projections similar to bastions. Used as a stand alone fortification with or without stockades/ palisades, or as part of a larger overall defensive system such as a corner bastion(s) for a stockaded fort.
A small fortified building, generally with an overhanging second story, used as a place of retreat or on the diagonal corners of stockades as a flanking device. A stockade was usually made of logs or heavy timbers; but other materials, such as earth and stone were commonly used in conjunction with wood.
a stronghold that is reinforced for protection from enemy fire; with apertures for defensive fire
a defensible post, usually rectangular, constructed to give shelter and protection to its garrison, consisting of possibly thirty men
a machine-gun and artillery emplacement pointed at the ocean
Small square fortification, usually of timber bond overlapping arrangement of bricks in courses (flemish, dutch, french, etc.)
A thick-walled building usually constructed of logs, with loopholes for muskets, designed as a center for defense. Bomb or Shell: An explosive projectile made of cast iron, detonated in flight or after penetrating the target by means of a fuse.
A fortified building, sometimes part of a larger fort, used as a barracks for the troops and as a strong point during an attack.
A small fortified work consisting of one or more rooms fitted with loopholes in its sides to permit defensive fire in various directions.
building constructed of heavy logs in the shape of a square, rectangle, or cross, to serve as a strong point for infantry or artillery. A ditch was often excavated around the exterior with the spoil thrown up against the wooden structure as a protection against fire and gunfire. Often part of the first floor of a blockhouse was below ground, while the upper floor, pierced with loopholes and embrasures, was built with an overhang so that defenders could fire down around the base of the structure. Blockhouses were used to defend railroad trestles, bridges, and depots, or served as a "keep" or place of final refuge in a larger fortress or stockade. The excavations associated with many blockhouses survive, although timbers were often scavenged for other uses. Some had brick or stone flooring and fireplaces.
Small square fortification, usually of timber bond overlapping arrangement of bricks in courses. The example shown upper right is a reconstruction of Fort Edward Blockhouse (1750), Windsor in Nova Scotia, Canada. The photo below is of Fort Blockhouse, Plymouth.
In military science, a blockhouse is a small, isolated fort in the form of a single building. It is intended to serve as a defensive strongpoint against any enemy which does not possess siege equipment or, in modern times, artillery. If a fortification is intended to protect against such weapons as well, it is more likely to qualify as castle or, in modern times, a bunker.
